Embodiment Construction

[0017] Related to the detailed description and technical content of the present invention, it is now described as follows with regard to the accompanying drawings:

[0018] Please refer to figure 1As shown, it is a schematic diagram of a device circuit according to an embodiment of the present invention. The present invention is a lighting device including a rectifier 10, a power conversion circuit 20, a light emitting unit 30 and a microprocessor unit 40. The rectifier 10 and a The external switch 50 is electrically connected, and the external switch 50 determines whether to obtain an external power from a commercial power supply. The external switch 50 can be, for example, a switch-type power switch (Wall Switch) installed on the wall, and the above is only an example. The present invention is not limited thereto. The rectifier 10 receives the external power and rectifies it into a high-voltage direct current. In one embodiment, the rectifier 10 includes a plurality of diod...

Abstract

The present invention discloses a lighting device and a light color control method thereof. The light color control method of the lighting device comprises the steps of: switching on an external switch to allow a lighting unit to emit low-brightness white light; determining the external switch is switched on or off at the time exceeding first interval time or not, and allowing a microprocessor unit to execute a work mode identification program; if the work mode identification program is determined as a first work mode, allowing the microprocessor unit to control the lighting unit to emit lighting white light; determining whether the external switch is switched on or off at the time exceeding second interval time or not, and allowing the microprocessor unit to control the light unit to emit a plurality of different light colors Cn; determining whether the external switch is switched on or off, allowing the microprocessor unit to control the lighting unit to emit light color Ci; and ifthe work mode identification program is determined as a second work mode, allowing the microprocessor unit to control the lighting unit to emit the corresponding lighting white light or the light color Ci.

Description

technical field [0001] The invention relates to a lighting device and a light color control method thereof, in particular to a lighting device with a memory function and a light color control method thereof. Background technique [0002] With the advancement of light-emitting diode manufacturing technology, the light color it emits is no longer only the traditional white color, but also various colors composed of red, green, blue and their combinations. Function In addition to illuminating the target to make it clearer, the use of changing the light color of the lighting device to achieve environmental layout, create an atmosphere, and hold entertainment activities is becoming more and more popular. [0003] For example, China Taiwan Invention Patent Announcement No. I540934 proposes a LED lighting dimming circuit, which controls the dimming of LED components, and is characterized in that it has: a power supply terminal, which supplies the power supply voltage; a ground term...
